"Still, there’s no question Slack is on a roll. As of December, it disclosed it had more than two million daily users, four times more than a year ago, and more than 570,000 of those were at organizations paying for their subscriptions. It’s taking over office communications at small- and mid-sized companies, but it still needs to break into bigger companies."

Looks like Thred will focus on top down "bigger companies" approach to adoption through MS channels and let that flow naturally down to "small and mid sized companies" effectively replacing Slack.

Slack have not yet established themselves as the dominant player in B2B at the top level. Opportunity for Thred and our advantage capitaliser is MS.
